Free breast x-ray screening will be available to Goldfields women 45 years and over from August this year.
Goldfields Minister Ian Taylor said the extension of the State Government's screening mammography program to the Goldfields would be brought forward by 12 months in response to public demand.
Mr Taylor said the existing Great Southern network would be extended to cover Southern Cross in July; Coolgardie, Leonora, Leinster and Laverton in August; Kalgoorlie-Boulder and Menzies in August-September; and Kambalda, Norseman and Esperance from October this year.
The mobile units are staffed by a radiographer and receptionist.
In Kalgoorlie-Boulder, two radiographers would be employed to work extended hours to cover shift workers and older women unable to attend a mobile clinic during the working day.
The dates for the visiting service would be advertised in the local media in advance of clinics in each centre.
Mr Taylor said the program offered a screening service to women considered to be at greatest risk of developing cancer of the breast, ie; those aged between 45 and 69.
"Early detection greatly improves the chances of successful treatment," he said.
One in 14 women will develop breast cancer and last year 200 Western Australian women died of the disease.
More than 40,000 screenings have already been performed throughout the State since the $6 million program was established four years ago.
